CO2 incubators are categorized into water jacketed and air jacketed types based on heating systems. Water jacketed models use surrounding water layers for superior thermal uniformity and slower temperature loss during power outages, ideal for long-term cultures. Air jacketed incubators employ direct-heat technology for rapid temperature recovery and simpler maintenance, excelling in frequent-access applications. Both maintain critical cell growth conditions (37°C, 5% CO2, 95% humidity) for resea
